Application filed October 12, 1915. Serial No. 55,538. 1

To all whom it may concern: Be it known that I, CORYDON J. Pn'rnrn,

a citizen of the United States, residing-at Geneva, in the county of Ashtabula and State of Ohio, have invented certainnew' and useful Improvements in Gas-Stoves, of.

which the following is a specification. I

This invention relates to certain new and useful improvements is gas stoves.

The primary object of this invention is the provision of a stove for fluid fuel and especially adapted for natural gas, the same being employable both as a heater and a cooking stove.

Another object of vide a gas stove provided with an extended area for the gas flame and having a tortuous path of travel for the products of combustion whereby the maximum quantity of heat is utilized in the stove before exhausting the products of combustion through the outlet flue.

A still further object isto provide a stove for natural gas which is easy to manufacture being constructed with a removable 'arrangement of gasdirecting partitions providing increased radiation, enhancing the efliciency of the stove, provision being also made to draw inwardly the cold air beneath the stove for warming the same.

WVith these general objects in view and others that will appear as the nature of, the

invention is better understood, thesame consists in the novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claim. x

In the drawings forming a part of this application and in which likeedesignating characters refer to corresponding parts throughout the several views :F igure 1 is a front elevation of the stove. Fig. 2 is a vertical sectional view thereof. Fig. 3 is a vertical transverse sectional View taken upon line IIIIII of Fig. 2. Fig. 4 is a horizontal transverse sectional view through the stove. Fig. 5 is a vertical transverse sectional view thereof taken upon line V-V of Fig. 2. Fig. 6 is an enlarged perspective view of the radiating frame illustrating its position within the stove. Fig. 7 is a horizontal transverse sectional view .of a circular formof stove embodying the present invention, and Fig. 8 is a perspective view of a portion of the latter.

the invention is to pro-' Referring more in detail to the drawings, a substantially cubical form of casing 10 is provided for one form of the stove mounted in substantially the usual manner upon 'four corner legs 11 and the said casing being prov1ded wlth a forwardly projecting dome 12 and with hinged front double doors 13 beneath the said dome.

A gas supply pipe 14: is horizontally positloned transversely through the casing 10 slightly above the bottom 15 thereof and is provided with diagonally arranged slits 16 upon its upper side for furnishing a burner for the stove positioned adjacent to a forwardly-fihclined baflie plate 17 secured to the casingjobottom 15 and extending in {spaced relations beneath the top 18 of the casing, the said plate being covered with a non-combustible fiber facing 19 such as as- -bestos.- The casing bottom 15 has an upturned portion 20 adjacent the burner pipe 14: leaving an open slot 21 beneath the said burner pipe for admitting air to the burner and assisting the combustion of the fluid fuel, the blaze from the burner being distributed over the plate facing 19 as the flame ascends.

A plurality of air tubes 22 are vertically arranged between the casing bottom 15 and top 18 having entrance openings 23 at the bottoms thereof and outlets 24 at theirtops. A detachable cover 25 is provided upon the casing with a projecting side bead 26 and a centrally ar'rangedknob or handle 27, while the said cover is provided with a plurality of perforations 28' after the manner of a radiator for allowing the heated air to escape therethrough as illustrated by arrows in Fig. 2 of'the drawings.

'.A frame is arranged within the casing 10 for performing the dual function of providing additional radiation as well as an extended path of travel for the products of combustion and the same consists of three spaced transverse plates 28, 29 and 30 arranged in parallelism and having perpendicularly positioned connecting plates 31 and 32 between the adjacent ones of said threeplates, the said connecting plates be ing of less width than the transverse plates as best illustrated in Fig. 6 of the drawing.

This radiating frame so formed is removarranged with a similar opening 3% at its opposite lower corner and the rear plate 30 has a similar opening 35 at its lower corner corresponding to the first-named plate open I ing An inclined baffle plate 36 is positioned between the rear plate 30 and the rear wall 37 of the casing 10 and has its lower end secured to the casing bottom adjacent the said plate opening 35, while an outlet pipe 38 is provided for the products of combustion communicating through the casing wall 37 at a point beneath the said plate 36. It will thus be seen that by igniting the fluid fuel such as gas at the burner slits 16 of the inlet pipe 1d, the plate facing 19 will be formed in a sheet of flame imparting heat to the stove, while the products of combustion will pass rearwardly over the top of the batlle'plate l7 thence through the bot tom opening 33.0f the plate 28 and over the top of the connecting plate 31 and through the opening 3% of the intermediate plate 29 and thence over the-top of the connecting plate 32 and out through the bottom opening 33 of the rea'r plate 30 where the same will ascend as directed by the plate 36 and then descend and be exhausted through the outlet flue 38 of the casing. The heating of the radiating frame formed of the'plates heretofore mentioned as-well-as the heating of the casinglO generates a high degree of heat for any purposes desired, while the path of travel required of the products of combustion by meansof the'radiating frame allows substantially the entire heat to be utilized before the same is exhausted through the outlet fine 38. The heating of the air within the tubes 22 provides an upward draft therethrough for exhausting the cold air from beneath the casing 10 and heating the same within the tubes 22 for passing outwardly through the upper ends thereof and through the perforations '28 of the stove cover 25.

In Figs. Tand 8 a circular form of't-he stove is provided in which'the invention is also embodied and the samebroa'dly conof a cylindrical member having an outer cylindrical casing 39 and inner casing -l() arranged concentrically therewith, a to ll and a bottom 42 being arranged for the same. A plurality of air tubes l3 are vertic-ally arranged connecting the top and bottom members l1 and 4:2 for opening at both ends for allowing the air to pass therethrough. A burner a5 is arranged within the casing at the forward side thereof, while an outlet pipe 4-6 is arranged at its rear side. 'lransverse partitions ll are arranged spaced apart between the said pipes a3 and the said burner t5 and outlet to. the partitions adwfardly arranged burner around the partitions i-l until they pass outwardly throughthe rear flue l6, the air pipes d5 carrying the heated air upwardly through the stove and exhausting the same at the top thereof into the room. i v

The invention therefore as shown by the embodiments thereof herein illustrated, pro vides an eliicient heating means for a stove casing adapted for the utilization of fluid fuel and is economical in its use by reason of its conservation of a high percentage of the products of combustion emanating from the burner. I

\Vhile the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that'minor changes may be made therein without departing from the spirit and scope of the in vention as claimed.

-ll'hat I claim as new is:

A stove including a casing, a burner pipe arranged therein adjacent one end, a forwardly inclined bathe arranged adjacent the burner extending from the stove bottom to a point adjacent the top thereof, a plurality of spaced partitions positioned transversely of the stove and. extending from the bottom to the top thereof, alined partitions positioned longitudinally of the stove between the transverse partitions a nd. extending .from the bottom of the stove to a'point adjacent the top thereof, an inclined baffle positioned in the compartment between the rear wall of the stove and. the rear transverse partition, and vertical air flues between the trans- 'verse partitions at opposite sides of the bailles, said transverse partitions having openings at the lower corners thereof, the openings in adjacent partitions being at opposite sides thereof to cause a tortuous passage ,of the heat from the burner.

In testimony whereof I affix my signature in presence of two witnesses.
